The influence of n ‐butyl group position upon the fragmentation behavior of the three isomeric n ‐butylcyclohexanones was studied. The different fragmentation processes are described and have been applied to the differentiation of the positional isomers of long‐chain n ‐alkylcyclohexanones. In the case of the 4‐ n ‐alkyl isomers, an interesting mechanism involving a recyclization is proposed and substantiated by deuterium labelling.
